Henkel brings out injectable thermally conductive adhesive for EV battery systems

Source:Adsale Plastics Network 2023-06-08

Henkel Adhesive Technologies is dedicated to help solve the challenges of OEMs and battery manufacturers to accelerate the transition toward zero-emission mobility. Therefore, the company has extended its broad portfolio of solutions for EV battery systems with a first-of-its-kind injectable thermally conductive adhesive.


The new adhesive Loctite TLB 9300 APSi provides both structural bonding, as well as thermal conductivity in the battery system. The product has already been adopted by one of the world’s largest EV battery manufacturers.


Designed for applications such as bonding battery cells to modules, or bonding cells directly to cooling systems, Loctite TLB 9300 APSi is a two-component polyurethane thermally conductive adhesive with a high thermal conductivity of 3 W/mK, moderate viscosity, and self-levelling characteristics.


In addition to its heat management properties, it delivers a unique combination of good electrical insulation with high bonding performance to a variety of substrates.


Henkel launches new injectable thermally conductive adhesive for EV battery systems.

As a solvent-free solution that cures at room temperature without the need for additional energy consumption, it helps customers advance their sustainability agenda by reducing emissions and resource use, while also ensuring safer working environments.


“Loctite TLB 9300 APSi is a testament to Henkel’s continued efforts to innovate new e-mobility solutions tailored to solve today’s battery manufacturing challenges and enable the next-generation designs of tomorrow. Its immediate adoption by a major battery manufacturer demonstrates our close partnership with key players in the e-mobility industry to help advance change,” said Holger Schuh, Global Senior Manager Thermal Technologies at Henkel.


Loctite TLB 9300 APSi also demonstrates Henkel’s deep expertise and experience in the critical area of thermal interface materials for EV battery systems, which are vital to the enablement of safer and higher performing EVs. Due to its precise application, enhanced design flexibility and improved bond strength, the first-of-its-kind injectable thermally conductive adhesive offers the benefits of a simplified manufacturing process.


“Thermal management in EV batteries is still one of the biggest challenges for electrified mobility. New designs targeting higher energy densities in battery packs bring along the requirement for multifunctional thermally conductive adhesives instead of classical thermal gap fillers," added Stephan Hoefer, Global Market Strategy Head for E-Mobility at Henkel.


"Leveraging our strong innovation capabilities at Henkel, we have started to launch a family of materials varying in thermal conductivity, bonding strength, elasticity, and application methods to address those new requirements.”
